Area of a rectangle = Length x Breadth
[tex]\begin{gathered} \text{Length = 2}\frac{3}{4} \\ \text{ = }\frac{11}{4} \\ \text{Breadth = 1}\frac{1}{2} \\ \text{ = }\frac{3}{2} \\ \\ \text{Area of a rectangle = }\frac{11}{4}\text{ x }\frac{3}{2} \\ \text{ = }\frac{33}{8} \\ \text{ = 4}\frac{1}{8}feet^2 \end{gathered}[/tex]
